Those look good Nat - we do have a stock of Argos drills but frankly I'd rather have a source of gearboxes/motors than have to keep pulling drills to bits and throwing a bunch of bits away, even if it's not much cheaper (can probably find an alternative home for the complete drills!). Agree with Jamie that having complete gear/motor assembly is preferable too, and also the shape of the gearbox case looks a bit less like the inside of a particular drill.

Couple of questions:
- Any idea how reliable the supply is going to be? Could this be a long-term replacement for the Argos/Mylek drills, or might future shipments be different? Not so bad when using mounts like yours, but I like the idea of integrating the mount into the robot chassis so it would be nice to be able to count on getting the same shaped box every time!
- Would it be possible to order them with 18V motors as well as with 12V?

On a bit of a FW hiatus due to the local Hackspace being closed but I'd say we'd be interested in six or so of these if they're in the £10-15 price range.
